I guess that's one day per digit in the usual pi value 3.14159... oh wait! They're one day short!!!
I tried to order the MSP-EXP430FR4133 under the Pi-week special which requires entering a coupon code to get the "special" price. No go. It says the code is expired. The Pi-week page says it is good until the19th, so it should have worked.
Of course there's no way to reach TI since everything is closed over the weekend.
I bet I can find something on eBay that will ship today for less money!
